OP2 MQTT? - Opie91 - 2019-10-31
Have been getting to know OP2 over the past few nights and it all looks great.
The only thing I cannot seem to find/figure out is MQTT. Does OP2 address this or do we just install it outside of the OP2 architecture.
Thanks for any help!

A local MQTT server (mosquitto) will be installed with openplotter-actions app. Still in development.

Thanks Sailoog!
RE: OP2 MQTT? - Opie91 - 2020-03-02
Any word on when we will see the IoT app?
RE: OP2 MQTT? - Sailoog - 2020-03-02
not yet, sorry. That is next on TODO list
RE: OP2 MQTT? - Opie91 - 2020-03-02
That is great to hear, Thanks!

How is the IOT app going?

I think a few of us are waiting for this.

The first steps have been done in openplotter-iot but now we are focused to finish the openplotter-sdr-vhf app.
IoT app will use Signal K notifications and we have to test deeply this SK server feature before keep working.

Maybe I've misunderstood what you are waiting for but I have installed the SignalK-mqtt-gw plugin through the SignalK appstore.
This instals a local broker and I now have 5 x ESP8266 devices sending and receiving with Openplotter/SignalK using MQTT.
I also send/Receive MQTT through a public broker for remote systems monitoring.
Im no coder but it works great and I'm happy to share more details if requested.
Simple example NR Flow below
